For you roulette collectors out there, here's what I've seen so far.
Tables: M, N, P, Q, R, S, T, V are in the main areas of the casino. Tables X & Y are in the high-roller room. I did not see O, U, or W. The old casino left off at "L."
I only saw 7 colors: tan, dark brown, olive, dark blue, gold, lavender, maroon.
